I noticed that some pets start out with more hit points than others. How does the tamer keep up on healing the lower hit point pet during training when up against the unbound energy vortex? Or, does the tamer have to settle with the lower creatures to kill and just "slightly" gain battle experience? Nightmares, for example come to mind. They start out their hit points around 300 or so, but the Cu's start out around 550-600. Seems that the nightmare would be harder to keep alive during battle against a tougher creature.
